Frank Muller discovered NGC 7220 = LM 2-466 in 1886 with the 26" refractor at the Leander McCormick Observatory. He reported "mag 15.5, 0.2' dia, vlE, gbM, *10 precedes 3.2' in PA 5° (NNE). There is nothing at his position, but 1.0 min of RA east and 2' north is ESO 532-028. A mag 12 star 3' north matches his description. Herbert Howe measured an accurate position in 1897-98 with the 20" refractor at the Chamberlin Observatory in Denver.

400/500mm - 17.5" (8/8/91): very faint, very small, irregularly round, gradually weak concentration. A mag 15 star is 1' N and a mag 12 star lies 3.0' N.
